Robinson met the 17-year-old girl online, and Robinson told her he was a police officer, Cook County Assistant State’s Attorney Oscar Garcia has said.

During the June 26 encounter, Robinson is said to have detained the girl by holding her hands and wrists above her head and not allowing her to leave, according to Cook County court documents. He forced her into unwanted sexual acts and, according to the criminal complaint, continued to kiss and bite the alleged victim on her lips and breasts.

Robinson’s employment status with the Cook County Sheriff’s Office is pending the outcome of an internal investigation and administrative hearing.

“What happens to his employment is yet to be determined,” Cook County Sheriff’s Office spokeswoman Sophia Ansari said.

Robinson was “de-deputized” after his arrest, meaning that he had to turn in his gun.

He has been employed with Cook County since 1990 and remains on the sheriff’s office payroll, Ansari said. He earned $34.54 an hour and was stationed at the Cook County Jail in Chicago.
